There is a lot of info about this dosing method in the archieves. It is basically a method where the schedule more closely mimics what the bodies own would be w/out cah. From what I have read the largest amount of hydro is given very early 2-3 am and then the dosed get smaller thoughout the day. I will be switching to this method when K starts pre-K so as to avoid giving meds at school. I would go to the archieve boards and read up on it there, I know several people have input there and I believe there is also a link to a site on circardian as well. Best of luck, assk if you have more questions.
Peace~Tina
